Today I finished up the newest plane in my hangar. It's a replacement for the one in my avatar which was destroyed a week ago due to an aileron servo failure (still my fault, though). I made a few needed improvements to this one and it came out two ounces lighter and significantly stronger

This picture gets the idea across, but it was too dark to get any good shots by the time I had her totally done today.

have a few hk 3d hawks and the last one i extended all the control arms and put two servos on the ailerons.cut foam away so you get absolute max throw on everything..This plane turns inside out on high rates, can crawl along or zoom around. You can run the battery flat doing summersaults on the spot for 10 minutes full throttle with no ill effects. wing flex is out of control to watch and you have to carve enough of the ailerons so as not to snag on fuselage when diving and spinning. can be taken out with carbon spar...but why would you when it cracks you up as it flys so great trying to snap its own wings off. It won't happen though, for the price it is a blast of fun. climbs straight,hovers. knife edge fly inside and out. can even cope with a breezy day if your good enough. Before you buildone of these it is a must to tape all the front vertical and horizontal surfaces right back to cock pit. Now it will handle crash after crash with ease you break the motor out but just keep hot glueing back in..Sweet

it must have been really dark, because you seem to have missed a bit of covering near the empennage

She's a scratchbuild. I think the closest plane on the market is the RadicalRC E-Hornet, which was a significant (and somewhat obvious) influence on the original design.

As for the uncovered tail, I really just like the way it looks. What you almost don't notice are the scalloped trailing edges of the ailerons and elevator which seem simple but are a real bear to cover

I flew her today. Everything went well, but she needs a bit of adjusting to be perfect. Still needs iron crosses for the wings, too.

Here's a pic of the finished product just before the very successful maiden. A buddy of mine says he can make me some crosses for the wings (maybe the tail, too, if I ask nicely ) so I've probably got that covered now.

After trying unsuccessfully to fly my new Wild Hawk ($50 on sale ) with stock power, I removed the brushed motor/ESC and replaced with a HURC 370 Zoom brushless motor and 30 amp ESC.

I didn't want to use a solid block in the pylon hole for a motor mount as that would block the air flow to the motor. I found a piece of 1 1/8" OD aluminum tube in the garage, which was a perfect match for the diameter of the brushed motor. For mounting the new brushless motor, I cut 4 tabs in one end of the tube and bent them out and drilled them for screws.

The addition of an air scoop to cool the ESC and battery seemed like a good idea, so I cut a hole in the canopy and adapted a plastic spoon to form a scoop. For the outlets I used two pieces of carbon fiber tube into the lower sides of the fuselage to draw air through the scoop and out the bottom.

The 240 watts (measured) will take this thing vertical almost forever!

Added rubber-band wing retention to the Dynam Cub...the OEM latch was pulling loose and the wing was loose on the fuselage. Also, added a proper landing gear (made for a larger plane) along with 3" DuBro wheels.
It tracks great, less flex means less ground-looping, and with the wing held tight, flying manners are more consistent.
